Step-by-step explanation:

a.c=2πr

c=2x3.142x50

c=100x3.142

c=0.03142

b.c=2πr

286=2x31/7xr

286=62r/7

286x7=62r

Leokris [45]

We are given here the individual costs of DVD and CD as well as the total sales and the number of items sold on one day. To solve the number of DVDs and CDs sold each, we devise two independent linear equations:

(1) x + y = 39

(2) 4x + 7y = 204

x- number of DVDs; y - number of CDs

solving, x= 23 DVDs

a) Little book LTD earning per share is $1.118 per share.

Explanation:

To calculate earning per share we will use following formula: $\frac{NET INCOME}{WEIGHTED AVERAGE SHARE OUTSTANDING}$

Now to find net income we will take help of asset turnover ratio : $\frac{NET SALES}{TOTAL ASSET}$

NOTE : LET x BE THE NET SALES DURING THE YEAR.

Asset turnover ratio = $\frac{x}{860000}$

1.5 × $860000 = x

x (net sales) = $1290000

Outstanding shares = 75000 shares

So Net Income = $1290000×.065

= $83850

Now Earning per share = $\frac{83850}{75000}$

Earning per share = $1.118

b) Market to Book Ratio will be 1.2 for Little Book LTD.

Explanation:

Market to Book Ratio = $\frac{MARKET CAPITALIZATION}{TOTAL BOOK VALUE}$

Market Capitalization = $ 75000× $ 12

= $900000

So, Market To Book Ratio = $\frac{900000}{750000}$ = 1.2

So , Market To Book Ratio is 1.2 for little book ltd.
